Unable to add Cloned VMs to FSRM

I created a VM and then cloned it using Netapp Rapid cloning utility as well as also tried to create a VM from a templete. Now when I try to add these VMs in FSRM it gives me an error saying host already exists (88). When I researched on NOW site this kind of error gets displayed with Simulators as they have same serial number however I could not find any documentation regarding the VMs or server with FSRM. It seems as I cloned those VM some unique identities also got cloned which is being checked by FRSM and thus it is just detecting one VM in spite of multiple VMs. I have also made the entries in DNS but still facing the issue. I would request if anyone has faced this kind of problem and knows the magic trick to fix it.
